How to Get AWS Account Id using Python Boto3
AWS provides the Security Token Service or STS that usually lets you request temporary credentials for your IAM users or federated users.
AWS STS also exposes an API called GetCallerIdentity that gives you the details about the IAM user or role whose credential is used to call this API. Boto3 provides you with the same functionality using get_caller_identity() method of the Client that represents STS.
In this section, I’ll show you how to get your AWS account Id using Boto3. As you expect, we will use get_caller_identity() method.
Let’s start
Create an STS Client & Get AWS Account Id using Boto3
Create a new folder or python project and create a new file get-account-id.py
Let’s start adding code to it.
1. Import boto3 and connect to STS service
Import boto3 and create an STS client.
import boto3
sts = boto3.client('sts')2. Call the client.get_caller_identity() method
Now that we have a client, we can call the method get_caller_identity() which is available to the STS client.
response = sts.get_caller_identity()The get_caller_identity() method returns the response which is a dictionary.
Try printing the response and you will see something like the below-
{
'UserId': 'AIDAZZFUGMQ4PHIPEWRED',
'Account': '123456789012',
'Arn': 'arn:aws:iam::123456789012:user/dummy@gmail.com',
'ResponseMetadata': {
'RequestId': 'bf0019a9-9749-4f83-a1f4-7c70d869d551',
'HTTPStatusCode': 200,
'HTTPHeaders': {
'x-amzn-requestid': 'bf0019a9-9749-4f83-a1f4-7c70d869d551',
'content-type': 'text/xml',
'content-length': '420',
'date': 'Mon, 19 Dec 2022 08:26:07 GMT',
},
'RetryAttempts': 0,
},
}
3. Pick Account Id for your purpose
In the above response as you notice, the Account key has your account Id. You can pick the account Id from the python dictionary by using the key name Account as shown below-
account-id = response["Account"]Final Code to Get AWS Account Id using Python Boto3
So this is our short and sweet example code in boto3 to get your AWS account Id.
import boto3
sts = boto3.client('sts')
response = sts.get_caller_identity()
print(response["Account"])Once you run this Python file, you should be able to see the accountId as you can see in the screenshot.
Conclusion
In this tutorial, we learnt how to get AWS account Id using Python Boto3. First, we learnt about AWS Security Token Service or STS which provides the method get GetCallerIdentity that returns the details about the user/role that was used to call this API.
Later we used AWS SDK for Python or Boto3 to connect with STS and call this API to retrieve the account ID.
